Barbecued chicken takes longer to cook and loves lower cooking temperatures. The trick to good BBQ chicken is patience. Done right, it will take at least an hour, and even up to 2 hours. Remember that BBQ is slow and low, grilling is hot and fast. You can grill a chicken breasts, but chicken thighs, legs or wings are far better barbecued.
The key is to moderate your heat. Either set the coals of the grill all on one side so you have a cool spot, put the chicken on the top rack of the grill, farther away from the heat, or, if you have a gas grill, just turn the heat to low. Slow and steady makes the best BBQ chicken. Sauce should only be applied in the final minutes of grilling. This prevents the sweet sauce from becoming burned or scorched.
